Currently I am researching on topic modelling using LDA...
I came up with an idea to contextually map abbreviations to a context.
Eg. Rh is right hand as well as rhodium. Depending on the context I want to map.
I have written a small algo that will find the reference of the word in the existing text and replace it. But I have to retrain my NER to achieve it so the accuracy is not not good.
